Abstract:Pisha stone is the main cause of soil loss in Yellow River,the area between Shannxi,Shanxi,Inner Mongolia contributes 70% sand by 17000 km2 ,so it is the core of treating Yellow River . Hydrophilic Polyurethane（W-OH curing agent)is a kind of hydrophilic organic material synthesized by polyether and TDI. Gel produced by W-OH material and water can bond pisha stone, meanwhile it also has the features such as easy-operative,low-cost,contamination free.This experiment is about researching the properties of curing material by changing the temperature.By analyzing infrared spectrum,curing viscosity curve ,SEM pictures,we can acquire the best properties change solution,which is benefit to the production and application to W-OH material.

1.Infrared spectrum analysis is used to analyse the groups and molecular structure of curing materials.

2.Viscosity analysis is used to analyze curing time.

3.SEM is used to check the micro-structure pre and after experiment.

Key words: W-OH Curing Agent ;pisha stone,change;SEM
